Using this approach, we have discovered a large number of novel proteins subject to β-secretase cleavage in two human epithelial cell lines.
Furthermore, over-heating of A2ML1 in reducing-denaturing conditions results in its cleavage in two polypeptides of 120 kDa and 60 kDa ([15] and personal observations), which reduces the signal intensity at the expected electrophoretic migration.
We have found minimal caspase 3 cleavage in two of our four cell lines (OE21/OE33) and only marginal protective effects of caspase inhibition on viability in one cell line.
Here, we show that among four different 2A peptides, a 2A peptide derived from porcine teschovirus-1 (P2A) has the highest cleavage efficiency in three human cell lines, zebrafish embryos and mouse liver.
Here, we generated four expression plasmids each harboring different 2A peptides derived from the foot-and-mouth disease virus, equine rhinitis A virus, Thosea asigna virus and porcine teschovirus-1, respectively, and evaluated their cleavage efficiency in three commonly used human cell lines, zebrafish embryos and adult mice.
We found that 25-HC reduced SREBP-2 cleavage in all three prostate cell-lines, whilst compactin increased SREBP-2 cleavage in PrEC and LNCaP cells, but not in PC-3 cells (Fig. 2C).
As expected, the combinations of cladribine and S3I-201 induced strong activation of caspase-3 and -8, and PARP cleavage in all three MM cell lines.
While lapatinib induced low levels of caspase 3 cleavage in all three cell lines, the addition of EZN4150 increased cleaved caspase 3 and decreased P-Akt to a greater extent than was seen with either agent alone (Fig. 2a).
Given the observation of a significant elevation in Mcl-1 protein level without caspase 10 cleavage in all three MPM cells following PI alone treatment, we conclude that PI alone treatment is insufficient to activate the PFM and can induce only a limited apoptosis in MPM cells.
In addition to ionomycin-induced calcium flux, tumor necrosis factor (TNF -α also sTNF -αted clealsoe in both two- and three-dimenstimulatedroblast cleavage.
